SPECIFICATION formingpart of Letters Patent No. 715,533, dated December9, 1902.

Application filed September 20, 1902. Serial No. 124,168- (No model.)

as will enable others skilled in the art to which it appertains to makeand use the same.

My invention relates to certain new and use-.

ful improvements in frames for eyeglasses.

It has for its object to provide a frame which shall be not only compactand capable of being folded within the boundary of that portion withinwhich the lenses are confined, but which when extended and in use tosupport the glasses upon the wearer shall take bearing upon that part ofthe anatomy of the head where there is an absence of movement resultingfrom the articulation of the jaw-bones and at the same time not pressupon any of the nerves,thus rendering the use of theglasses lessobjectionable than is the case with frames as ordinarily constructed.

With these ends in view my invention consists in the details ofconstruction and arrangement hereinafter more fully set forth.

In order that those skilled in the art to which my invention appertainsmay know how to make the same and fully understand the advantages of myimproved frame, I will proceed to describe the construction thereof andits adaptability to the anatomy of the head, referring by letters andfigures to the accompanying drawings, in which- Figure l is a side viewor profile of a portion of a human head and showing my improved frameproperly located for use, the dotted lines in the illustration of thehead indicating so much of the bone anatomy as is required toparticularly illustrate the predetermined proportions and constructionof the bows of my improved frame and the advantages resulting therefrom.Fig. 2is a top view of my improved frame with the bows in extended oropen position, and Fig. 3 is aplan view with the bows folded down uponthe lenses.

Similar characters of reference denote like parts in the severalfiguresof the drawings.

to 3 they are slightly curved, as best illus-- trated at Figs. 1 and 3,and the end is then fashioned into a substantially rectangular eye 4,with the upwardly-trending portion slightly curved, as shown, for thepurpose presently explained. As shown at Fig. 2, that portion of the bowfrom the point 1 to 4 is curved slightly outward to conform to thegradual outward curve of the frontal bone 5, and the eye 4 is formed soas to rest in the correspondingly shaped cavity existing between thefront and rear boundaries of the malar 6, as shown at Fig. 1, and at apoint unaffected by the articulation of the mandible 7 with the squamoustemporal 8 and also away from the influence of the squamous and othersutures represented by the zigzag lines at Fig. 1. With thisconstruction the nose-bridge B and bows O cooperate to hold thelens-frames in proper relation to the eyes of the wearer, and as theeyes 4 at the extremities of the bows 0 rest behind the front ridge ofthe malar bone 6 and are in a position to be entirely unaffected by thearticulation of the bones or the movements of the sutures it will beapparent thatno appreciable inward pressure of the ends of the bows isnecessary in order to maintain the frame in proper position, and henceno inconvenience is experienced by the wearer.

The bows O are made of substantially uniform length, and any slightvariation in the bone formations of various persons may be readilycompensated for by slightly varying the extent of the curvatures from 1to 3 and 1 to 4, hereinbefore referred to, so that in every case theeyes 4 of said bows may be located in the depression or slight cavity inthe malar 6.

I am aware that it is not new to construct eyeglass-frames with a hingedor articulated nose-bridge and comparatively short bows provided withcups adapted to rest upon the temples; but in this construction thejoint in the nose-bridge precludes the proper cooperation of the sameand the ends of the bows to properly maintain the frame in position, andthe bows are not constructed with special reference to the bone anatomyof the head, but, on the contrary, terminate and press at a localityWhere they are subjected to the influence of articulative motions anddepend for security of position upon undue and irritating pressure uponthe temples, where extreme sensitiveness prevails.

What I claim as new, and desire to secure by Letters Patent, is

1. An improved eyeglass orspectacle frame, consisting of thelens-framesrigidly connected by a nose-bridge, and side bows hinged to thelens-frames by a joint of limited movement, said bows curved to conformto the convexity of the frontal bone and provided at their free endswith substantially rectangular eyes at such predetermined distance fromthe hinge-joint as to rest when in use, in the cavity existing betweenthe front and rear boundaries of the malar bone of the skull,substantially as hereinbefore set forth.
